Why Olympic swimmers wear multiple caps in the pool
為什么奧運會游泳運動員要戴兩頂泳帽？
One of the most amusing moments during the opening week of competition at Paris 2024 occurred in the pool.
2024年巴黎奧運會開幕周最有趣的時刻之一發(fā)生在游泳賽場上。
It saw a middle-aged volunteer dressed in colorful trunks dive into the water to receive a lost swimming cap before lapping up applause from the crowd.
一名身穿花色泳褲的中年志愿者跳入水中，撿起丟失的泳帽，此舉贏得了觀眾的掌聲。
The cap was believed to have been the property of Team USA swimmer Emma Weber.
這頂帽子被認(rèn)為屬于美國隊游泳運動員艾瑪·韋伯。
However, when the camera panned to the American, Weber was still wearing a cap.
然而，當(dāng)鏡頭轉(zhuǎn)向這名運動員時，她仍然戴著帽子。
This is because Olympic swimmers typically wear multiple caps when competing. But why?
因為奧運會游泳運動員在比賽時通常會戴多頂帽子。但這是為什么呢？
Why do Olympic swimmers wear more than one swimming cap?
為什么奧運會游泳運動員要戴不止一頂泳帽？
You might think that the simple answer is: In case one of them falls off.
你可能會認(rèn)為答案顯而易見：以防其中一頂泳帽掉下來。
That is partly true but not quite the full story.
這個答案算正確，但不完全正確。
There are two main reasons why Olympic swimmers wear two - or sometimes more - caps.
奧運會游泳運動員戴兩頂泳帽，有時甚至更多，主要有兩個原因。
One is that wearing multiple caps can help to stabilise an athlete's goggles.
其一是戴多頂帽子可以幫助穩(wěn)定運動員的護目鏡。
As well as adding additional tightness, a second swimming cap can help cover up the exposed straps around the goggles, thus making the athlete more streamline and reducing drag.
除了增加額外的緊度外，第二頂泳帽還可以蓋住護目鏡周圍暴露的帶子，使運動員的服裝更加貼合流線型，從而減少阻力。
Most athletes will sit their goggles on a swimming cap made from latex, before adding a silicone cap on top.
大多數(shù)運動員會把護目鏡套在乳膠泳帽上，然后再在上面戴一頂硅膠帽。
The friction between the silicone and the latex should, in theory, make it much less likely for the top cap to fall off.
理論上，硅膠和乳膠之間的摩擦應(yīng)該會大大降低泳帽脫落的可能性。
